Its low-iso performance and also the fact that it takes AA's is what has it in the lead.
I agree, upgrade the body, it will upgrade all your lenses. You won't go wrong with either a K-x or K20. They'll both give you shake reduction, more pixels, much faster handling, dust control and better ISO performance compared to your K110. I'd say forget about the K10, the K20D is a very similar body with significant improvements.
I have a K20D and K-x and I disagree with you about low ISO performance. IME the K20D wins there. The K-x is almost a stop better at high ISO and offers significantly better AF in low light. Compared to the K-x, the K20D has a larger and brighter viewfinder for improved MF, more sophisticated controls, weatherproofing and more pixels for cropping. According to test results the K-x has greater dynamic range, but in practical usage I've not seen any advantage. The K-x is smaller than your current body, the K20 is larger. I prefer the larger size most of the time as it is better balanced with larger lenses and has a nicer grip, but a K-x with a pancake lens is a sweet little deal. I can see preferring AA's, I like them too, but I've never had trouble with the K20 power. The K-x pricing will likely be lower. The K20D went down in price just after the K-7 was announced, but then it crept back up and new ones are becoming scarce.
